Koreal solves issues with the introduction of an inventory management system.

We would like to introduce a case study of the implementation of the inventory management system "Koreal" at Tosa Dyeing Co., Ltd., a manufacturing company. Previously, inventory management was done through handwritten analog methods, but as the first step towards digital transformation (DX), we decided to implement the cost-effective "Koreal" inventory management system. After the implementation, we achieved DX in inventory management by sharing inventory between the headquarters and each factory. We registered "Headquarters and Each Factory" as a major category for storage locations and registered "Employee Names" as a subcategory. The "Koreal" inventory management system allows for "unlimited" additional account registrations and "free account registration," enabling us to register "all employees" for secure usage. We successfully reduced procurement costs for materials, which was a management challenge, by "13.6%." **Case Overview** ■ Effects - Time savings have been achieved for monthly inventory checks and year-end inventory audits. - Real-time data updates are possible with the "QR code function." - Centralized management has been made possible with the "inventory history function." *For more details, please download the PDF or feel free to contact us.*

[Instructor] Shintaro Fukasawa, President of BM Consulting Co., Ltd. Business Mathematics Educator [Key Lecture Content] There are things we somewhat think about. However, when asked for our opinions, we hesitate to speak up because we dread being questioned with "What is your basis?" This is a growing issue among business professionals. Shintaro Fukasawa, the only advocate of business mathematics in Japan and a business mathematics educator, identifies the inability of modern business people to articulate their thoughts and ideas as a "symptom." He finds commonalities between mathematical thinking and verbalization, and has developed a verbalization framework that anyone can easily practice. This content has been compiled into a book titled "How Can an Idea Become 'My Opinion'? - A Class to Turn Intuition into Logical Opinions" (2023). In this session, we will extract the essence of that book and explain how to create "logical and communicative opinions." You will take home tips that will dramatically change your business communication starting tomorrow.
